Speculation

Charlie, who holds the Arkendish, is able to communicate through the Eyebook to ParsonErf-b1-p100, but presumably without an Eyebook of his own. This may be due to the Arkendish's ability to provide an attuned user with "unmatched" Thinkamancy, or an even more dangerous ability of the Arkendish to hack into presumed secure Thinkamancy-based communications. He may also have been able to create an Eyebook equivalent by hiring casters from the Magic Kingdom.

Real World References

Eyebook is a homophone to iBook making it a reference to a line of Apple products such as the iPod, iPhone, and of course the iBook.

All of the eyebook update notification sounds are old Classic Mac OS system sounds:

Stanley = Quack

Parson = Wild Eep

Wanda = Droplet

Sizemore = Indigo (probably)

Interestingly, Charlie's sound effect is not a Mac sound; its the "tada" sound from Windows, which might be a joke on the fact that he's not supposed to be part of the network.
